PACKING FOR BOTTLES Filed Oct. 18, 1952 "will Patented Dec. 10, 1935UNITED STATES PATENT OFFICE PACKING FOR BOTTLES Application October 18,1932, Serial No. 638,434 In Great Britain August 26, 1932 Claims.

This invention relates to a packing for bottles and of the kindcomprising a pair of pressed complementary shells of cardboard or thelike having a row of bottle-shaped depressions turned 5 alternately inopposite directions and formed in said depressions with reinforcementflutings.

One object of the invention is to increase the strength of the packing,and the invention consists in this respect in arranging the flutings ofcontiguous depressions in a relatively staggered position and ininterrupting the flutings so as to form a plain, straight rib in thecentre of each depression and a plain, intact edge between twocontiguous depressions.

" i A further object of the invention is to ensure a better protectionfor the bottles, and in this respect the invention consists in formingthe shells with end supports for the bottles so as to preventlongitudinal as well as transverse displacement of the latter.

Fig. 1 of the accompanying drawing represents a plan view of part of thepacking shell according to the invention,

Fig. 2 is a section on the line II-II of Fig. 1

including a bottle,

Fig. 3 is a section on the line III--III of Fig. 1,

Fig. 4 is a perspective view on a reduced scale of part of a shell,

Fig. 5 illustrates in cross-section, the overlapping of the flutings ofcontiguous depressions along a line corresponding to 55 in Fig. 1 in amodification having no end flanges, and

Fig. 6 is an enlarged detailed cross-sectional View of the packingstrip, similar to Fig. 5, at and near the edge between contiguousdepressions.

The packing comprises a pair of complementary shells which may beinterconnected and which are pressed into shape from cardboard or other,preferably yieldable, sheet material and formed each with a row ofbottle-shaped depressions 2, turned alternately in opposite directions.This sheet material may be formed by a plurality of webs of papersheeting reinforced and glued together by such adhesive material as asodium silicate solution. Only one of the shells is shown in thedrawing. Each depression is formed with reinforcements in the form oftransverse fiutings l, extending along the complete length of thedepression and across substantially the complete width of the packingstrip. In accordance with the invention, the flutings or corrugationsare interrupted so as to leave a straight plain rib 3 in the centre ofeach depression as well as a plain, intact boundary edge 4 between twocontiguous depressions wherewith to meet the corresponding edge of thecomplementary shell. To increase the reinforcement, the flutings ofcontiguous depressions are relatively staggered as shown in Fig. 1, theapices on the inside of one depression being prefer-ably centrally in- 5terposed between corresponding apices of the contiguous depressions. Theribs in the deepest portions of the depressions as well as the plainedges at the tops thereof serve to impart a desired degree offlexibility to the packing strip 10 without affecting the permanence orstability of the fiutings. Thereby an effective cushioning of frangiblearticles is obtained by means of the packing strip according to theinvention after repeated use thereof. The fiutings in each de- 15pression, although interrupted by the rib 3, are in continuous alignmentand are not displaced upon opposite sides of the rib. This featureresults in a stronger as well as more economical manufacture. 20

To prevent longitudinal displacement of the bottles 7, end supports areprovided consisting of a semi-annular flange 6 for the bottom end of thebottle and a semi-circular plate 5 for the top end thereof (Figs. 2, 4).A fiat plateau 8 ex- 25 tends from the plate 5 to the edge of thepacking strip. Although these features are desirable, they are notessential for the realization of the basic advantages of the instantinvention.

Figs. 5 and 6 are enlarged sectional views of a 30 packing strip havingno end flanges. The mutual confinement of the bottles by the taperedportions of the'depressions is adequate to maintain the bottles inplace. In this embodiment a distinctly plain, raised edge 4 is formedbe- 35 tween the depressions which absolutely precludes any deformingeffects upon the offset reinforcing flutings upon a flexing of thestrip. With the corrugations or fiutings displaced in adjacentdepressions, the juncture thereof at any edge 4 be- 40 tween thedepressions presents no weak points which are conducive to a breaking ina direction transverse to the longitudinal axis of the depressions.

By these modifications of the packing, the bot- 45 tles will beeffectively prevented from clashing and breaking even if the packingcase should be rolled over or subjected to shocks.

I claim:

1. A packing strip for bottles comprising a5 formed unitary paper sheethaving a contiguous row of bottle-shaped depressions facing inalternately opposite directions with the boundary edges of eachdepression common with the boundary edges of adjacent depressions,corrurow of bottle-shaped depressions facing in alternately oppositedirections with the boundary edges of each depression common with, theboundary edges of adjacent depressions, corru-- gations extendingtransversely of the longitudinal axes of the bottle-shaped depressionsfrom points adjacent said boundary edges, said corrugations being inalignment in each depression and 'displaced with respect to thecorrugations in adjacent depressions, and merging into the plainboundary edges at the juncture of adjacent depressions, saidcorrugations being furthermore interrupted in their course betweenadjacent boundary edges to form at least one rib disposed symmetricallyin each depression.

3. A packing strip for bottles comprising a formed unitary paper sheethaving a contiguous row of bottle-shaped depressions facing inalternately opposite directions, with the boundary edges of eachdepression common with the boundary edges of adjacent depressions,uniform corrugations extending transversely of the longitudinal axesof'the bottle-shaped depressions from points adjacent said boundaryedges, each of said corrugations having an interrupted por-.

ti-on at the deepest portion of the depressions whereby a rib is formedin each depression, with the corrugations on the opposite sides thereofin alignment, said corrugations furthermore bein v displaced in adjacentdepressions.

4. A packing strip for bottles comprising a formed unitary paper sheethaving a .row of contiguous bottles-shaped depressions facing inalternately opposite directions with the boundary edges of eachdepression common with the 5 boundary. edges of adjacent depressions,uniform corrugations consisting of alternate ribs and grooves extendingtransverselyof the longitudinal axes of the bottle-shaped depressionsfrom points adjacent said boundary edges, each of 10 said corrugationshaving an interrupted portion at the deepest portion of the depressionswhereby a longitudinal rib is formed in each depression, with the seriesof ribs and grooves of said corrugations on the opposite sides of saidlon- 15 gitudinal rib in respective alignment, said corrugationsfurthermore being displaced in adjacent depressions so that the ribs inone depression are in alignment with the grooves in adjacent depressionsand the grooves in said one depression 20 are in alignment with the ribsin adjacent depressions, said ribs and grooves of adjacent depressionsmerging into the plain boundary edges at the juncture of saiddepressions.

5. A packing strip for bottles comprising a 251 formed unitary papersheet having a contiguous row of bottle-shaped depressions facing inalternately opposite directions with the boundary edges of eachdepression common with the boundary edges of adjacent depressions,substan- 30,:

tially uniform corrugations extending transversely of the longitudinalaxes of the bottlesha'ped depressions from points adjacent said boundaryedges, said corrugations being in alignment in each depression anddisplaced with re- 35".

spect to the corrugations in adjacent depressions, and merging into theplain boundary edges at the junctureof adjacent depressions.
